The Goodman 10123533 is the OEM manual reset limit switch designed for the GMH950904CXAE 96% AFUE gas furnace. This high-limit safety control opens the burner circuit if it senses excessive heat, protecting the heat exchanger and cabinet from overheating caused by restricted airflow, a failed blower, or a dirty filter. Because it is a manual reset device, it stays open after a trip until the red button is physically pressed — a deliberate safeguard that forces inspection before the furnace can fire again.
The genuine 10123533 is calibrated to the exact trip temperature Goodman specified for this furnace, ensuring the safety trips at the correct threshold — not too early (nuisance shutdowns) or too late (unsafe). Generic switches with mismatched setpoints can undermine this protection. For a life-safety component, OEM is non-negotiable.
Easy to Moderate (2/5). Around 15–20 minutes. Cut power at the disconnect, note and disconnect the two wire terminals, remove the mounting screws, and install the new switch in the same orientation. Reconnect the wiring, restore power, and press reset. If the switch trips again after replacement, investigate the airflow or blower fault causing the overheat.
